Class Random

constructor

• new Random(_seedOrFunction?: number | Function): Random

  Create an instance of Random. If a seed is given, LFIB4 is used as generator, reproducing a series of numbers from that seed. If a function producing values between 0 and 1 is given, it will be used as generator.

  Parameters

  • Optional_seedOrFunction: number | Function

  Returns Random

getColor

• getColor(): Color

  Returns a color with its r, g, b values set to random numbers in the range of [0, 1[.

  Returns Color
